This inventionhas; relation toj hose-nozzles; and-it'consists in -theconstruction and novel arran gem ent of a nozzledesigned to be screwedon the freeend of a discharge-pipe, and provided `with large and smallwater-ways, in combination with a valve to close one when the other isopen, for a purpose `hereinafter described. It also coisists incomhining with a nozzle a hinged handle` or` keyand a slotted cap forprotecting this key from blows, having stops arranged for the purpose ofallowi ing the valve to be opened quickly, and, at

the same time, preventing it from being closed suddenly, and therebygiving an injurious blow to the hose. My invention also consists in thenovel Construction of a detachable cap for throwinga spray, and inproviding the Valve-case with a screw-seat for holding the cap when notin use, all as hereinafter shown and described. i

In the annexed drawings, the letter A designates my improved nozzle,which is designed to be screwed upon a supply-pipe, and is provided witha small water-way, J, and a large water-way, J', for the purpose ofthrowing a large and a small stream. B designates a valve-seat of theform of a conical frustum, arranged at right angles to water-ways J Jand designed to receive a plug-valve, G, ot'

. corresponding form,'through which are made,

at right angles to each other, orifices D E, one of large and the otherof y small size, adapted to register, respectively, with the large andwith the small waterways J `J The smaller fln nanr HIS 5 RIGHT "TO HE-ALLEN FIRE' DEPARTMENT SUPPLY' ooM Specifieation foiifihg part ofLetters Patent N 70,138, dated Novenber`16, 1875; application fi e i 4 ua -i i Octoher23,1875. A v a i end of valve-plug B is provided `with aeentral polygonal projection, c, which `passes through an opening on the'correspon'din'g end of the' valve-seat, and is securedthereto by meansof a screw, s, passing nto a'threaded recessin the sad'projection, and awasheror nutfl, of suitable shape, whichis passed over e theprojectingend of the projection c, and-hears against the end of 'theoasing i or seat, *and thus serves asa clamp for taking up'wear.

The other end of this valve is provided with another projection, b, towhich is hinged` or cates `a metallic plate, which is secured 'onthelarger end 'of' the valvecase, and ,coversthe 'operating-handle d, whichprojects' through sl'ot, s', formedin the' side of `the said cap i forthe *purpose- This cap is sufficiently strong to protect -theogerating-armd from being broken by a casual shock occasioned by.

a fall or other accident, and it is provided upon its under side with anangular downwardly-projecting lug, i, situated intermediately to twosimilar lugs, ?3 i )rojecting upward from the valve-case, which lugs aredesigned to act as stops or guides to regulate the discharge of waterfrom the large waterwayJ', and to cut it ofi' entirely from both thesmall and the large water-ways. will be accomplished in the followingmanner, to wit: The nozzle beingattached to the supply-pipe by means ofa screw-threaded coupling, Gr, on its larger end, if the Operating-leverbe thrust to the left to a position just outside of the lug i the smallorifice in'the valve will be brought registering with the smalleduction-way J in the nozzle, causing a small stream to be thrown.thrust to the left as far as possible the small stream will be instantlycut ofi', and the large one also, ths stopping the flow of wateraltogether; but if, now, the lever d be thrust to the right, past lugs i6 i to the opposite end of slot s', the large opening in the valve--plugThis a If the said handle be v will 'register-accurately with the largeeduct J( in the ozzle, and a very large stream Will be produced. Shouldthis stream prove eX- cessive it may be reduced slightly by thIustingthesaidlever to theleft back against lug ?7 more by `thrusti ng it incontact wi th the central-lug i', stili farthei* when moved to lug i',

and finally cut off altogether by causing it to pass the said lug iwherthe very small stream before described as issuing from the smalleduct J will be restored. i The lugs, as shown in Fig. 3, are of angularform, one face being perpendicular to the length of the slot, and the.other at an -nclination thereto, thus greatly facilitatin g whateverchanges may be requisite in the position of lever d for producin'g theabove-described streams.

-'It wi11 be 'seen in practice that, the perforations-D E in the valve-Obeing at right angles to 'each other, itis impossible to have a smallstream and a large one at'the same time, as, 'when perforation D isopposite the large .water-way J ',.the smaller Water-way J is' 'cutoff-and no water can pass through. The large water-way is to be used incaseof fire, whilethe smaller-vone is intended for the purpose of spinkliug the street and washing the pavemenm I; desgnates a rose cap, whichis intended' to be 'used for the purpose of throwingasprayfand isdesigned to be screwed on theend of large water-way J", ahove'described,and'L designates a screwseat *on"` the reduced-end of the valve-case,which'- is-designed to hold-this rose 'when not in use; L'-desi gnatesja" detachahleannilus,

which is intended tobe screwed on and serve asa' protection to'thescrew-seat L when the cap-'L is on-the screw-threaded end of the largeway. This annulus and rose are interchangeable, and when the rose is onthe large' water-way J' the annnlus may be on the screw-seat and thereverse;-

Rose I consists of concentric` spaced rings or annuli j, which areeach of the general shape of the frusturof a cone, as shown incross-section, Fig. 1, and are arranged in an inverted position, and aresupported from he low by means of diametrical hridge's l l', subtendingthe screw-threaded rim h, 'so when the stream is turned on 'it dvergesin every direction from the center, and spreads over a broad surface.
